Application March 8, 1954, Serial No. 414,908 7 Claims.(Cl. 266-23) (Granted under Title 35, U. S. Code (1952), see. 266)burning equipment and more particularly it relates to an attachment foruse with mechanized burning equipment that permits the cornoletion of aburning operation in one uninterrupted traverse of the burningequipment.

Where the need arises to modii a structural member such as an l-beam bycutting away either part or all of one side or both sides of one of itsflan es along the entire length of the beam, resort is usually had tomechanized burning equipment. To perform the burning operationexpeditiously, a metal burning torch or a pair of metal burning torchesis mounted on a mechanized crse ec' hreat. The mechanized traverseequipment generally includes a carriage provided with power drivingmeans and further includes a plurality of rollers driven by the powerdriving mea s to propel the carriage along the length of the structu lmember. The metal burning torches are adjustably secured to thecarriage. As the carriage moves along the length of the structuralmember, the metal burning torches are adapted to separate by burning theundesired portion(s) of the beam along its cn.'re length from the mainbody of the beam. The torhcs are attached to one end of the carriage.When the m .chanized equipment is at the beginning of its traverse whichis at one end of the beam, the burning torches are positioned to begincuttting away the undesired portions of the beam beginning at the oneend of the beam. However, it is possible to perrorm the entire burningoperation along the entire length of the beam in one continuous traverseof the carriage. if the carriage were to continue moving when itapproached the end of the beam opposite the starting end the carriagewould drop right off the end; even at that the torches would still nothave completed tie burning operation along the entire it is aconventional procedure, at present, to stop the carriage as itapproaches the end of the beam, extinguish the cutting torches, take thecarriage oil the end of the beam, turn the carriage around, and thenremount it on the beam so that it is ready to complete the burningoperation by starting from the end opposite the starting end and movingtoward the starting end. Tie burning torches thereby are able tocomplete the burning operation.

This invention marss a departure from the prior art in that it providesan extension adapted to be conveniently attached to the end of astructural beam prior to the beginning of the burning operation. Theattachment provides an extension of the supporting surface for therollers of the mechanized traverse equipment. The attachment hassupporting means at one end and a convenient attaching means at theother end for securing the attachment to the structural member in analigned relationship therewith. The attachment is designed toaccommodate a range of sizes of beams.

An object of this invention is to provide an attachment for use withburning equipment.

A further object is to provide an attachment for use with burningequipment that is adapted to eliminate the need for reversal of theburning equipment prior to completion of a burning operation.

A further object is to provide an attachment for use with burningequipment permitting a complete burning operation once the equipment isset up.

A further object is to provide an attachment for use with mechanizedburning equipment to permit a complete burning operation in one traverseof the burning equipment.

Ot 131 objects and many of the attendant advantages of this inventionwill be readily understood by reference to the following detaileddescription when considered in connection with the accompanying drawingswherein:

The single figure shows a preferred embodiment of the attachment of thisinvention partially broken away and secured to one end of a structuralmember only a part of which is shown on the drawing.

There is shown on the drawing an attachment 10 for use with mechanizedmetal burning equipment. For purposes of illustration and not in anylimiting sense, the attachment it is shown secured to one end of anelongated structural l-beam 11, having an upper flange 12; only a smallbroken away portion of the I-beam 11 is shown on the drawing. The end ofthe I-beam 11 is not altered in any manner prior to securing theattachment It) thereto.

The attachment it) includes an extension 13, preferably in the form of asection of T-beam. The section of T beam 13 is of a lightweight metal orother strong material. Lightweight material is preferred so that it maybe handled easily in transferring it from one workpiece to anotherworkpiece. Aluminum has been found to be suitable. The section of T-beam13 has a web 14.

Securing means, generally shown at 15, is provided for securing theattachment 1t) relative to the beam ll. The securing means 15 includes aright-triangular section or flat plate 16. One of the perpendicularsides of the section of flat plate 16 is welded to the web 14 of T- beam13 adjacent one end thereof so that the former and the latter arecoplanar. The side of the section of flat plate 16 perpendicular to theside welded to the web 14 is aligned with the end of the web. Welded toeach surface of the right-triangular section 16 is an attaching means17. Each attaching means 17 includes a longitudinal leg 21 and atransverse leg 26. Threadedly engaged Within tapped holes in thetransverse legs 26 are bolts 13, 19, and 2h. The clamping bolts arearranged to engage the web of the beam 11 when the latter is disposed inthe space between the attaching means 17. Additional bolts 27 arethreadedly engaged within tapped openings in the ends of longitudinallegs 21. 'By virtue of their position, bolts 27 not only engage the webof beam 11 for the purpose of clamping but in addition serve to alignthe attachment 1t) longitudinally relative to beam 11. Set screws 22 arethreadedly engaged in tapped holes in transverse legs 26. The set screws2?. serve initially to engage the web of beam 11. Being of the sockettype they may be conveniently manipulated simultaneously to align theweb 14 of the section of beam 13 with the web of beam 11.

Each of the transverse legs 26 is further formed with a cutout 24adapted to receive the ends of the lower flange of beam 11. By thisarrangement it is possible for the attachment it) to be used with agreater range of sizes of I-beams than would otherwise be possible.

Shields 23 are adjustably secured to the longitudinal legs 21 of theattaching means 17. The shields 23 are flat copper members. They areformed with elongated slots 25. Fastening screws 29 are passed throughthe elongated slots 28 and are threadedly engaged within thelongitudinal legs 21 for retaining the shields 23 in fixed relationshipthereto. The elongated slots permit the shields to be adjusted accordingto the thickness of the web of beam 11.

Since the weight of the attachment 1% plus the weight of a mechanizedburning equipment is too heavy for the attaching means 16, an auxiliarysupport 25 is provided for the attachment 10. The auxiliary supportincludes a pair of telescoping members 31 and 32 and thumb screw 33.Telescoping support 25 is pivotally secured to the T-beam 25 by a pivot34. The thumb screw 33 on the telescoping support 25 permits foradjustment of the supporting end 32.

In operation, the attachment 19 is first brought in o position at theend of I-beam 11 manually and then while holding the attachment 1% sothat the surface of the flange of the T-beam section 13 is substantiallycoplanar with the surface of flange 12 of I-beam 11, the set screws 22are tightened against the web of the l-beam 11. Through simultaneousmanipulation of the wrenches engaged in the sockets of the set screws,the end of the web 14 of the section of T-beam 13 is aligned with theweb of the I-beam 11. The attachment 10 is then aligned longitudinallywith respect to the I-beam 11 by selective tightening of the bolts 27.When the bolts 27 are finally tightened the attachment 10 is partiallysecured. Subsequently, the bolts 18, 19, and 20 are tightened to finallysecure the attachment 10 to the I-beam 11. The copper shields areadjusted by loosening the screws 29 and sliding the shields to theirinmost positions abutting the web of the beam 11. As the mechanizedburning equipment proceeds along the beam 11 and approaches the endshown on the drawing, one end of the equipment approaches and comes intoengagement with the attachment 10. Motion of the mechanized burningequipment continues until the burning operation is completed along theentire length of the beam 11. At that time the mechanized burningequipment is brought to rest entirely on the attachment 10. As the metalburning torches pass over the shields 23 the attaching means 17 isprotected against the flame of the torches by the copper shields 23. Bythis arrangement the burning operation is completed in one traverse ofthe equipment without the need for additional handling with consequentloss of time.

Obviously many modifications and variations of the present invention arepossible in the light of the above teachings. It is therefore to beunderstood that within the scope of the appended claims the inventionmay be practiced otherwise than as specifically described.
